The verdict in three sentences
In e-commerce, refund speed signals trust as strongly as delivery time. In Kenya, an M-Pesa refund via B2C API lands in 2 to 6 hours, while a manual reversal on many wallets takes 24 to 72 hours. With a refund-request rate around 4.5 % and a 14-day policy, refunding under 24 hours can add up to +12 NPS points.
Why processing times vary so much
It all comes down to the channel: a manual refund (an agent sending money back from a wallet) is slow and error-prone, whereas a reversal API automates and timestamps the operation. Operators do not all offer the same technical maturity.
| Operator (2026 order of magnitude) | Refund time | Reversal fee | Channel |
|---|---|---|---|
| M-Pesa (B2C API) | 2-6 h | 0-1 % | Automated |
| Airtel Money | 6-24 h | 0-1 % | Semi-auto |
| MTN MoMo | 24-72 h | 0-1 % | Manual/API |
| Orange Money | 12-48 h | 0-0.5 % | Semi-auto |
| Card (via PSP) | 3-10 d | 0 % | Banking |
A card refund stays the slowest: the banking rail imposes 3 to 10 days. Well-integrated mobile money beats the card here.
The business impact of a fast refund
A quickly refunded customer stays a customer. A dragging refund generates messages, disputes and negative reviews that drag down conversion.
| Metric | Refund > 72 h | Refund < 24 h |
|---|---|---|
| NPS impact | -8 pts | +12 pts |
| Customer repurchase rate | 18 % | 41 % |
| Support tickets/100 orders | 9 | 3 |
| Related negative reviews | frequent | rare |
| Escalated disputes | 2.5 % | 0.6 % |
Refunding fast costs less than managing dissatisfaction: every avoided support ticket saves time and protects reputation.

Mini case study
Ibrahim runs a fashion store in Nairobi, 700 orders/month. At 4.5 % refund requests, that is 32 refunds/month. Handling them manually (48 h average), he generates about 6 support tickets and 1 negative review per month. Moving to a reversal API (8 h average), he drops to 2 tickets, saves agent time and sees repurchase rise. On an average basket of KES 4,000, recovering just 5 customers a month = KES 20,000 in extra revenue.
FAQ
Why does M-Pesa refund faster than MTN MoMo? M-Pesa has a mature B2C API that automates the reversal in 2 to 6 hours, whereas many MoMo flows remain semi-manual and take 24 to 72 hours.
Does a mobile money refund carry a fee? Usually 0 to 1 % depending on the operator. That is marginal compared to the cost of a lost customer or a negative review.
What refund policy should I display? A 14-day window is a reassuring standard. What matters is announcing a realistic processing time and keeping it.
How many refunds should I plan for? Expect around 4.5 % of your e-commerce orders. On 700 orders, that is roughly thirty refunds to process each month.
Does refunding fast really improve loyalty? Yes: a refund under 24 hours can add up to 12 NPS points and more than double the repurchase rate versus a delay over 72 hours.
